4. Run:
pim ipv6 holdtime join-prune interval
The value of the Holdtime field in the sent Join/Prune message is set.
The Holdtime period is the period for keeping the Forwarding/Prune state of the
downstream interface.
5. Run:
pim ipv6 require-genid
The Generation ID option is set in received Hello message.
The Hello message without the Generation ID option is refused.
The change of the Generation ID in the Hello message received from the upstream
neighbor indicates that the upstream neighbor is lost or the status of the upstream
neighbor has changed.

13.8.3 Configuring Control Parameters for Prune
The prune control parameters can be set either globally or on an interface. The parameters specify
the delay for transmitting messages in a LAN and the interval for overriding the Prune action.
Context
The Hello message carries lan-delay ( which indicates the delay for transmitting prune message )
and override-interval ( which indicates the interval for overriding a prune ). The relationship
between lan-delay, override-interval, and PPT is that lan-delay + override-interval = PPT. Prune-
Pending Timer (PPT) indicates the delay from the time when a switch receives the Prune message
from the downstream interface to the time when the switch performs the prune action to suppress
the forwarding of the downstream interface. If the switch receives a Join message from a
downstream switch within the PPT, the switch does not perform the prune action.
Do as follows on the PIM-SM (IPv6) switch:
NOTE
The configuration of the control parameters of prune involves the following cases:
l Global Configuration: It is valid on all the interfaces.
l Configuration on the interface: The configuration on an interface takes precedence over the global
configuration. If the configuration on an interface is not done, the global configuration is used.
Procedure
